How to use Burn in a run

Burn rewards repeated application. One large stack falls away, while frequent smaller applications keep the pressure active.

1. Check the trigger condition.Range, Crit, cast, target, Rush, Stall, and quest requirements decide whether the effect appears at all.
2. Check the first application.Timing can matter more than the final stack count, especially against an opening threat.
3. Separate trigger from amplifier.Confirm the team can create the effect before buying equipment that only improves it.
